Designed for residential construction and newly built homes, the WhisperValue DC is considered an idealmultifamilyventilation with a new set of features that enable easy code compliance and longer service life, the company said in a release.

The advanced ECM motor with intelligent self-adjusting SmartFlow technology senses the amount of resistance in the duct run and automatically adjusts the fan speed to deliver optimal CFM output, even in the case of a complicated duct run.

Panasonic’s SmartFlow technology moves more air using less energy, so the WhisperValue DC is more energy efficient and lasts longer. Additionally, the Built-in Pick-A-Flow speed selector provides the capability to customize the ventilation fan for a variety of applications and to meet requiredairflow(50-80-100 CFM) with the simple flip of a switch. The ability to choose the most fitting CFM level gives builders and contractors the flexibility and assurance that one fan will satisfy a range of ventilation design requirements that meet code and perform as promised, officials said.

WhisperValue DC offers optional built-in features that allow the installer to further customize the fan:

·Multi-speed with time delay, which allows the selection of proper CFM settings to satisfy ASHRAE 62.2 continuous ventilation requirements. The fan runs continuously at a preset lower level (0-30-70, in 10 CFM increments) then elevates to a maximum level of operation (80 or 100 CFM) when the wall switch is turned on. A High/Low delay timer returns the fan to thepresetCFM level after 20 minutes.

·Condensation sensor, which helps control bathroom condensation to prevent mold and mildew. The advanced sensor technology detects relative humidity and temperature to anticipate dew point, automatically turning the fan on to control humidity. Built in relative humidity (RH) sensitivity adjustment enables fine tuning for moist conditions and for satisfying CALGreen requirements. The fan will run for 20 minutes before turning off.

The thin profile opens up new options for locations where builders and contractors can install the WhisperValue DC, which is UL listed for ceiling or wall mount. The low profile, 3-3/8-inch housingdepthand unique L-shaped bracket allow this fan to be installed in virtually any ceiling or wall. Wall installation reduces cost by eliminating the need to incorporate a radiation damper when penetrating fire-rated ceilings.
